Quaternary ammonium salts as inhibitors of acetylcholine esterase

Biochimica et Biophysica Acta, 1951
Abstract Quaternary ammonium salts show practically no inhibition of the hydrolytic action of liver esterase. They protect ACh estrase against inrreversible combination with TEPP, although the two types of inhibitors attach themselves to different points of the active surface. Quaternary ammonium salts also inhibit the hydrolysis of uncharged esters (
